Product data sheet
tiede PWL-1
red penetrant
General Description
Benefits
PWL-1 is a water-washable and solvent-removable red
colour-contrast penetrant that provides maximum reliability
in locating surface-open flaws and defects. It produces
vivid red indications of flaws which can easily be seen with
the naked eye.
• Outstanding penetrating characteristics
Applications
PWL-1 is used throughout industry to detect surface
defects. Typical applications include castings, forgings,
leak testing, welds and general metal work.
It can also be used on non-porous ceramics and similar
materials; however, we do not recommend it for inspecting
plastic materials, as it may stain, soften or even dissolve
the base material under test.
Composition
PWL-1 consists of a blend of petroleum distillates, nonionic surfactants and an oil-soluble organic red dye.

Like all Magnaflux materials, PWL-1 is closely controlled
to ensure batch-to-batch consistency, optimum process
control and inspection reliability.
• Excellent controlled washability over a wide temperature
range and variable dwell times
• Water-washable and solvent-removable
• Broad range of applications
General Method of Use
• Clean and dry the test part. It must be free from oil,
grease and other contaminants.
• Apply PWL-1 by immersion dip, brush, flow on, or
conventional or electrostatic spray. Make sure you
completely cover the test area.
•
Allow minimum penetration time of 2 to 5 minutes.
10 minutes is adequate for most situations., however,
lowertemperatures thicken the penetrant and require
longer penetration times.
• Remove excess penetrant by spraying the part with
clean water at 10°C - 40°C, or wipe with a lint-free cloth
dampened with RL-40.
•
Make sure the compnent is dry and apply a developer
by spraying. We recommend DL-20, our quick-drying,
solvent-based developer which will maximise sensitivity
and provide a white contrasting background so red
indications can easily be seen.
•
After inspection, you can remove developer residue by
wiping with a cloth or by a water and detergent wash.
Penetrant residues can be removed by vapour degreasing
or a solvent soak.
